IPC: C04B24/26
Filed: 1988-02-16
Abstract: PURPOSE:To obtain the title admixture (fluidity enhancer) with high-performance cement-dispersing ability along with little drop in workability with time, by incorporating the original admixture with a quaternary nitrogen-contg. product prepared by reaction of a quaternarizing agent with a copolymer from each specific compounds. CONSTITUTION:Firstly, a water-soluble copolymer with a molecular weight of 500 to 200,00 is prepared by copolymerization between (A) 20-80mol% of a compound of formula I (R1-R3 are each the same or mutually different 1-4C lower alkyl or H) and (B) 20-80mol% of a second compound of formula II (R4 is 1-4C lower alkyl or H; M is alkali metal, ammonium, amino or H). Thence, this copolymer is made to react with a quaternarizing agent such as glycidyl trimethylammonium chloride to prepare a quaternary nitrogen-contg. product. This product is then spiked with the original admixture to obtain the objective admixture.

Moreover, the connection of the metal films 14 to the electrode films 3, 4 can be carried out after the cover 8 has been set. Therefore, a matching adjustment can be easily conducted in a wide frequency range without destroying the sealability.

Title: Correcting system of font
Inventor: WATANABE AKIHIRO
IPC: G09G5/22
Filed: 1992-02-21
Abstract: PURPOSE:To improve a recognition rate of an OCR, by correcting a font of a letter to be printed by a printer. CONSTITUTION:A letter printed by a printer mechanism part 13 is recognized by a recognition part 22 and whether or not this recognition result is attained to a fixed recognition rate is decided by a diagnosis program part 31. As a result of this decision, when the recognition result is not attained to the fixed recognition rate, a font correcting program part 32 instructs the printer control part 12 to correct the font. The printer control part 12 corrects the font of a printed letter according to this corrective instructions. Since the font of the printed letter is corrected like this, even in the case where a fresh printing device is introduced, the recognition rate of an OCR can be kept at the fixed recognition rate by a user side and lowering of the recognition rate can be prevented.

Title: Calculating method for bending angle of plate and bending angle controller by utilizing this method
Inventor: MIYATO SEIYA
IPC: B21D5/02
Filed: 1988-02-19
Abstract: PURPOSE:To compute and control the fending angle of a plate high in precision and reliability by setting an acoustic wave radiation detector to detect sound occurring when the plate is bent, to a lower tool of a bending device. CONSTITUTION:Acoustic wave occurring when the plate is bent is detected by an AE (acoustic emission) sensor 6 set to a die 3 to input an AE signal to a preamplifier 7.

The analytical data 202 from the memory 9 is divided into two, one is a signal 203 smoothed by an all-wave rectifier 11 through a band-pass filter 10 and the other is a signal smoothed by an all-wave rectifier 12. The signals 203, 204 are computed by a divider 13 to obtain a desired power ratio. A set value and a data 205 from the divider 13 are compared in a comparator 14 and when the set value and the data 205 are equal, a motor 16 is driven and a cylinder rod of a hydraulic cylinder 17 is operated to control the position of an axis D.

Title: Radio line setting method
Inventor: HARADA HIDEO
IPC: H04W76/02
Filed: 1991-02-05
Abstract: PURPOSE:To set the optimum radio line by making a difference between a value of setting a receiving level for a radio line connecting a mobile radio apparatus and a fixed radio apparatus and a value of setting a receiving level for disconnecting the mobile radio apparatus and the fixed radio apparatus to discriminate the setting or the disconnection of the radio line between them. CONSTITUTION:Fixed radio apparatuses 3a-3n are connected to switch 1 that is connected to a communication network via wire line. Here, a mobile radio apparatus 4 sets radio lines between the mobile radio apparatus 4 and fixed radio apparatuses 3a-3n that sent a response signal thereto, and if there are a plurality of response signals, the sent relevant response signals are selected from radio apparatuses 3a-3n. Further, when a receiving level drops and trouble occurs with communication as the radio apparatus 4 moves, the radio apparatus 4 disconnects the radio lines. Further, radio apparatuses 3a-3n that received radio wave sent from the radio apparatus 4 detect whether or not a receiving level exceeds a threshold level. The radio apparatus 4 sets up a radio line with one of radio apparatuses 3a-3n that detected a call and sent a response signal earliest. Now, by making a difference between a receiving level setting value for setting a radio line and a setting value for disconnecting the radio line, the optimum radio line is set up regardless of the presence or absence of a control station.

Title: Electronic shutter for photoreceptive cell
Inventor: KNEE DEREK L
IPC: H04N1/107
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of information in a photoreceptor, which is obtained under a condition with a comparatively low S/N ratio by prohibiting the storage of an electric charge generated by means of a light in an integration capacitor till a reading device ends the reading of stored light signals from the integration capacitor. SOLUTION: An electronic shutter 31 is formed by an NMOS transistor 53 and a PMOS transistor 55. When a high logical signal is received from a node shutter, the transistor 53 becomes a conductive mode and the transistor 55 becomes a nonconductive mode. In the mode, an electronic shutter circuit 31 is a closed mode and the integration capacitor 30 does not store the electric charge generated by the light. Therefore, the electronic shutter circuit 31 is constituted to be the closed mode in order to end a storing period. The integration capacitor 30 holds the electric charge till it is read during the closed mode. Thus, the circuit 31 attains sufficiently controlled storing.
